To all 'Lo/tom t may Be it known 'that l, Francis lEenergie'son, a subject of the Vming Britain and Ireland, and a resident o'dgeWood Park, in the county of ifiilegheny end' State of Pennsylvanie, have made e new and useful Invention in Fluid-"Pressure Turbines, of which the olloving; is speciilcation.

This .invention relates to fluid pressure motors and moi e y ticularly to means for admitting fluid oressere (hereinafter called steam) from. a high nressure motor to a low pressure motor;

, One of the objects ot invention is to provide means whereby a governor or other load responsive device will control the admission of steam to the iow pressure motor.

Another object ot this invention is to provide means whereby "he louv pressure motor will receive steam from a low pressure sup .ply until such time as the load upon that motor becomes great enough to demand augmentation of the normal iiuid supply, when additional steam will be delivered to the motor from a high pressure source,

'lhefinvention is herein illustrated as being' applied to a multi-st-igeelastic fluid turbine which reeeiressteam from theexhaust of a high pressure engine. rlhe valve mechanism, illustrative oi one embodiment of my invention, is so arranged thatE when the load on the turbine is lightor lsuch that the steam delivered by the engine is in excess of the demand Yfor steam by the bine, a valve will be opened so as to bypass a portion'oij the steam troni the exhaust of the engine directly to the condenser so that the enfine will derive the benefit of eX- hausting at substantialljf' condenser' pressure. il'lhen tie load on the engine is light and the load on the turbine such that it demands more steam that is supplied hythe engine, live or high pressure ste-nn is automatlcally delivered 'to a high pressure stage ot' the'turbine` the exhaust steam from the high pressure engine being; delivered at the same time to a lower pressure stage ot' the turbine..

The valve mechanism is illustrated asf-on! trollod by a speed responsive govt-irnos', which operates through a. relay to impart the desired opening' and aliasingv movement to a byfpa'ss valve, arranged to admit steam Speeioationof Letters Patent.

`Figure 1 is a diagrammatic- View of e high pressure engine and e, turhine having,r suitable connection for conveying the steam from one to the other and provided with a Valve mechanism, Constructed in accordance with my invention; and Fig. 2 is an enlarged sectional View through the several valve casings and the Casing of a relafyu Referring to the drawings by numerals of reference: A iuid pressure motor 5, herein' shown as a reciprocating engine, receives motive iuid through a pipe or passage G `from any suitable' source of supply of high pressure Huid such, for example, as a steam generator not shown. rhe engine exhaust con'nnunicates with an exhaust pipe or pas sage 7, which in turn communicates with low pressure inlet port ot a turbine 9' through a branch pipe v8. The low pressure inlet port of the turbine eonnnunieates with7 and is adapted to supply motive fluid to a -low pressure stage ot the turbine.k

' haust pipel and, through the exhaustmani- Jfold '12 ot' the turbine, with a region of louY pressureor a condenser 13. The man1-4 fold 12 communicates directly with the oondenser 13, which, as illustrated serves for 'bothenrine 5 and turbine i). A relieil valve 14 is interposed in the by-pass piping 1l, A valve casing l5 is also interposed in a byp'ass l1 and inoloses a balanced valve 'lo which is adapted to seat on` a valve seat l? .The valve 1G is provided with a stem 13 on the upper end ot' which a spriug'seat 19 is mounted. A coiled spring; Z0 may surround the stem 18 and by operatingr between the seat ,19 and a seat formed on the valve casing; l5, tend to open the valve 1G. One end ot af-link 2S is pirotally secured to a bracket 24 formed on the spring seat k19 and the other end is pivotally secured 'to a lever 25, one end of which is pirotally connected lto a piston rod 2o.

A piston 27 is mounted on the rod 26 and is movable in a cylinder 28 .which is provided with the ports 29 and 30 at its respective ends. 4These ports alternately become inlet and exhaust ports according to the direction of movement to be imparted to the piston 27. The piston rod 26Y eX- tends through a guide 31, above the cylinder 28, and is threaded to receive a .hand wheel 33.

A lever 34 is fulcrumed on the piston rod 26 and is pivotally connected at the other end to a link which is actuated by a load responsive device; for example, a speed gov-` ernor 36 of the turbine. A valve .stem 37 of a relay device is pivotallyconnected to an intermediate point of' the lever 34 by nleans of an adjustable link 371. The stem 37 is provided with collars 38 and 39 which form valves in the relay device and control the operation of the piston 27. The valve 38 is adapted to close a port 40 in the easing 41 of the relay device, and the valve 39 is adapted to close a port 42, said portsv being supplied with liquid under pressure from some suitable source, such, for example, as an oil reservoir, through a port 43.-

The oil upon entering through the port 43 may pass through the ports 40 and 29 into cylinder 28 above the piston 27 or through the ports 42and 30 below the pis- `ton 27 and move the piston 27 in the desired direction, Exhaust ports 44 are provided in the casing 41 above and below the inlet ports 43 and the valves 38 and 39 and the valve stem 37 are so arranged and the ports 40'and 42 are so located that when one of the ports 40 or 42 is in communication with the port 43 the other will communicate with one or the other of the ports 44. This facilitates the movement of the piston 27 in one or the other direction.'

The lever 25 is connected by means of a link 46 to a lever 47, fulcrumed on a bracket 48 secured to the valve casing 49. The casing 49 incloses a valve 50, which controls and delivers high pressure steam to the turbine 9 when the low pressuresteam fromthe exhaust of the engine 5 isincapable of carrying the load on 'the turbine. The valve stem 5l of the valve 50 is connected to 'the lever 47 by means of a link 52 which is surrounded by a coil spring 53, the expansive force of which tends to close the val ve 50 and is greater than that of the spring 20 which surrounds the stem o fthe valve 16. The spring 53 has one end abutting ,against a` disk 54 carried by the" stem 51 and the other end abutting against an adjustable seat 55 mounted on a portion of the valve casing 'The valve 50 is balanced and ,controls the delivery of high pressure msteam through an inlet port 57 and outlet port 58. The inlet port 57- communicates Awith a source of. high'pressure steam through piping 59 `vtive position.

and the outlet port 58 communicates with .the inlet port 60 of the yhigh pressure stage of the turbine'9 through piping 61;

In the operation of the device as ,illus= trated,.it will be assumed that all 'the parts are at rest. Before starting the engine 5, the hand wheel 33 will be turned so as to raise the piston 27 and cause the valve 16 to be opened, the exhaust steam from the engine 5 will then pass through the by-pass piping ll'and the `valve casi 15 to the` condenser 13. After the engine 5 is in operation, the valve 10 may be'slightly opened to warm up the turbine 9 preparatory to starting it. Upon a further. opening movement ofthe valve 10 steam may be admitted to 'a lowpressure stage 62 of the turbine 9 vbut this steam will be unableto operate the turbine, inasmuch -as there is no substantiall differential of pressure between the pipes 7 and 12 withthe valve 16 in the wide lopen position. Inasmuchas the turbine is atrest, the'speed responsive device 36 is in a`positionl corresponding to the low speed position, and the valve stem 37 andthe valvesA 38 and 39 of the relay device are in their uppermost position and are 'admittingr oilf' to the cylinder 28 above the piston 27 Whih is .unableA to move downwardly because it'fis held in its uppermost position by vthe hand, wheel 33. In orderv to start the turbine the 1 hand wheel 33 may be turned t0 release thev piston 27 andto permit it to'move to such a position to cause. the partial closing of the valve 16 so that there is suilicient differ- 190 ential of pressure between the piping8 and exhaust of the turbine to start the turbine.

The hand vwheel-33 may be then raisedv until the turbine is up to normal speed, when it may be further raised to an inopera- A10 The valve mechanism will them become entirely automatic and lthe valves 16 and 50 will .be controlled wholly by the speed governor. 'V

By referring to the drawings, it will b e seen that .without the hand vfheel 33 and with the turbine at rest and he collars 38 and 39 in their uppermost position, that as' v soonv as the oil pressure isestablished the: piston 27 will be .forced downwardly, closing 1.15 the valve 16, then if the engine 5 were started with the valve 10 Aclosed there-IVQllld be no outlet for 'the exhaust steam, except through the relief valve 14.v If, on the other; hand, the, valve 10 were open, a full' charge ofthe steam would be admitted t0 thel tiir bine and lthe turbine might speed up too rapidly with the consequent ill eifect s When the turbine is operating at 1 o`w`` speed the lever 34 is movedbya governor 41 251 36 of the turbine, through the agency of the link'35, vtosuch a position that the valves 38 and 39 uncover the respective ports 40 and 42 of the relay device and place them in communication with the respective las ports 48 and 44. This admits oil pressure to the cylinder 28 above the piston 2T and exhausts the oils from below the piston. As the piston moves downwardly in response to the oil pressure, it irst closes the valve 16 in the by-pass vpiping l1 and then. it' a stilll further movement is imparted to the piston-27, the valve 50 is opened and admits high pressure 'steam thrbugh the piping 59 and G1 to the high pressure stage 63 of the turbine.

During the time that the piston 2A is rnoving down to close the valve 1G. the linl; lf3 acts as a fulcrum for the lever because the valve 50 is seated, due to the expansive fbrcebf the spring 53 and because the expansivelforce of the spring 53 exceeds the expansive force of the spring 20. [hitter the vvalve 16 A'has reached its seat the lever 253 fiile-ruins about the link Q3 and opens the 'valve 50 in opposition to the expansive force of the spring `When the turbine has attained normal speed the. governor 33 causes the valves and 39 to close the respective ports 40 and 42 so that the piston 27is locked in its lowest position b v the confined oil in the cylinder QS.' and the valve 50 is held open and live steainis delivered to theturbine. The valve 5i) is not essential to the' operation of the apparatus. but

, by employing it I insure thev opening of the valve 16 in oase of accident to the governor or to the valve operating mechanism.

If the load on the turbine now decreases the turbine will not require as much steani and consequently will speed np7 and7 through the agency of the governor 3b. will. move the valve stein 37 of the rela).v device to such a position that the ports l() and -l' are respectively placed in communication with theJ port fl?) and the exhaust port ell- Oil under pressure' is then delivereigl to the cylinder 28 below the piston 27 and the piston moves upwardly. The initial upward movement of the piston permits the valve 50 to close so that the turbine rcci-ives exhaust steam from the engine 5 only. ai'fter the valve 50 is closed the steam delivered to the turbine by the engine 5 is still in excess of the load demand on the turbine, the piston 2T will continue to rise until the valve 16 is unseated so as to pass seine ot the exhaust' steam from the engine `through the by-pass piping 1l into the condenser. lVhen the turbine again.encounters a heavy load, the valve 16 will be closed through the agency of the governor 3G. the relay device,

and the piston 27 and iil all the steam deliv-` ered by the engine is insuilicient to drive the turbine, the valve 50. will again be opened and live steam will, again be admit-'ted to the lhigh pressure stage, of the turbine. Ey admitting the high pressure steam to the *high pressure stage 63 of the turbine, the steam' 1s used more economically than if it wereA admitted, with the low pressure steam. to
